A Down-To-Earth Spectrum Analyzer and Oscilloscope

There are no ads you have to worry about with this app, it’s very straightforward to use, and it works exceedingly well with external audio interfaces like my IK Multimedia iRig 2, which is typically used with guitars and other musical instruments. Perfect for those of us who still like to repair tape decks, where precise frequency readings are essential, especially for motor speed and playback head azimuth adjustments.

The app was definitely a big help for replacing the belts on my Sony cassette deck from 1996. 👍

Good App

A decent free FFT app. I’m not sure of its accuracy, but that may be a factor of the iPad microphone too. It has an easy to use display, and clearly shows the peak of the spectrum, as well as a view or the waveform.

Easy to use but need to improve accuracy

App is very intuitive and free. It shows numerical values of frequency of peeks. However, the value is not super accurate. For example, the middle A sound is 440Hz. The app shows 441.4. And it’s happening on both my iPhone and iPad. So it’s very unlikely due to the microphone.
